[frontier] How do I design tools that agents actually use correctly?

Design tools for non-deterministic consumers: consolidate chained operations, namespace clearly, return only high-signal context, add \`response\_format\` options, and prompt-engineer tool descriptions as if explaining to a new teammate.

Journey Context:
Traditional API design assumes deterministic callers. Agents have limited context, can hallucinate, and may choose the wrong tool. Anthropic's 2025 guide showed that tool naming, description quality, and response shape have measurable impact on agent evaluations. The best tools hide implementation detail and present intent-shaped interfaces.
